Mr F,
The Sci-Fi Channel's 6-hour TV mini-series should be out on R2 DVD around November or December 2001.
The reason for the lengthy delay, is that the UK Sci-Fi Channel itself, is currently trying to obtain UK broadcasting rights to air this much-talked-about series. However, things aren't going too well, because the DVD company wants to release it on R2 DVD BEFORE the broadcast goes ahead, hence the whole thing is a bit of a fiasco.
Although I haven't seen the series, in general, the word has been relatively positive, considering the source material, and the 2 previous versions - the original 1984 movie, and the re-edited 3-hour TV cut.
If you are a big fan of the novel, then the TV series will not be that great in your eyes, but it is an improvement (plot-wise, at least) over Lynch's movie, from what I've heard! However, these words are to be taken as my opinion only.
